Title: Gate drive circuit for voltage driven switching element
Inventor: KIMURA ARATA
IPC: H02M1/08
Filed: 1999-12-03
Abstract: PROBLEM TO BE SOLVED: To make the suppressed amount of di/dt and dv/dt variable when an IGBT is turned off by a method wherein a power drop means is changed over to a power rise means according to the detected value of the operating state of a voltage driven switching element. SOLUTION: In a IGBT module 102 to which a gate drive circuit 101 is connected, the output of a drive means 107 which amplifies a signal used to control an IGBT so as to be turned on and off is connected to the gate and the emitter of the IGBT. In addition, a power rise means 105 and a power drop means 106 which make its output voltage transiently variable are connected in series with the drive means 107. The changeover of the power drop means 106 to the power rise means 105 is performed by the operating state (the collector voltage, the collector current or the gate voltage) of the IGBT. In this case, the changeover is performed at a time when the gate voltage which is set by a reference-voltage setting means 108 exceeds a reference voltage.  As a result, while the switching time or the loss of this voltage driven switching element is being suppressed, it is possible to restrain di/dt and dv/dt in the switching operation of the IGBT.
